ANNOUNCING Happy 1.16 - The LALR(1) Parser Generator for Haskell
I'm pleased to announce version 1.16 of Happy, the parser generator
system for Haskell.
Changes from version 1.15 to 1.16
* Switch to a Cabal build system: you need a recent version of Cabal
(1.1.6 or later). If you have GHC 6.4.2, then you need to upgrade
Cabal before building Happy. GHC 6.6 is fine.
* New %error directive
* New production forms: {%% .. } and {%^ .. }
* Added Attribute Grammar support, by Robert Dockins
NOTE: Happy version 1.16 is required for building GHC version 6.6 and
later.
Happy is available in source form (GHC 6.4.x or later and Cabal 1.1.6
required), and we also provide binaries for some architectures. The
Happy homepage with links to the various distributions lives at:
